Nothing is wrong, you cannot change the firmware in the radio remotely by using Smartlink. Its not a great idea anyway as if something happens (like you lose power halfway thru the update) how will you recover the radio? Its always been this way so nothing has changed in this regards.

Tried Hard Wire, no luck.... Ran a port scan and all checkout OK... Added a new switch to network, Did not Help... We will reset the flex to factory and install Ver 1.9xxx tomorrow and see what happens.

Make sure you don't have "port Isolation" (what ever your Router may call it) turned on which won't let the Radio and your Computer see each other on the local network.Another thing to try is have them both plugged into a separate Ethernet Switch, then the Switch to the Router.

Sign out of Smartlink . restart the PC, Make sure you have the latest firmware you want downloaded on the PC, start SSDR and select the radio from the chooser (or just double click on it) and connect. click upgrade when it comes up and let it complete.

We need some more info on exactly how you have your radio and PC connected, including connection to the router. Sounds like somehow you have multiple subnets there. Please give a description on how it is connected.

Ronnie... To log out of Smartlink:Click on the "RO" above the radio and you will get a new window to either save your login information or to logout of Smartlink. Then you can just use the SSDR Icon to get in and out of your radio on the local Lan. No "Smartlink" connection required.

Ronnie uses Spectrum (TWC) for his internet provider. The Spectrum modem has be put in full Bridge Mode by Spectrum with wireless disabled. Only port one (1) is used on the modem and it is sent to the input of the router. The routers/switch has only one cable connected to a new 10,100,1000 switch. All devices are using new CAT6 patch cables from one end to the other.

He is using an ASUS-RTAC66UB1 router to control his local area network. The DHCP is set to assign addresses from only 192.168.0.100 to 192.168.0.200 along with the correct subnet of 255.255.255.0 The router IP is 192.168.0.1 and all subnets are set to 255.255.255.0.

His PC has been put on a static address of 192.168.0.240. The Flex is set static to 192.168.0.250.

All the requires ports are forwarded to the PC including those for the Flex and also EchoLink. Doing a scan of the network shows all device on the proper addresses. All computers and wireless devices function correctly thru the router.

Important: The PC will not connect or even see the Flex while trying both a new Cat6 cable or a Cat6 crossover cable connected directly between the two devices.

Actually, I think he did..."Important: The PC will not connect or even see the Flex while trying both a new Cat6 cable or a Cat6 crossover cable connected directly between the two devices." Sounds to me like a bad Ethernet socket at either the Flex or the PC end...

The factory reset has been tried along with fresh installs after all previous software was removed from the computer.. Neither a Cat6 cable or a Cat6 crossover cable have been able connected directly from PC to Flex.. Neither worked and neither saw the radio. Yes we can ping the radio.

I moved the radio to my home and connected without error and did the upgrade without issue within minutes. When we returned the radio to Ronnie's it will only connect and run perfectly as a remote connections.

The issue seems to be in the software as it will only come up as Remote connection. We never have an option to connect with SmartSDR even with the network disconnected from the router. After the software and radio were updated it should connect without the internet, but they do not see each other on the LAN.

Please understand that I do large networks for a living and I have tripled checked this network. That is why he has new cables, switch and router. A complete new network with all new static IP addresses assigned to his computer and the Flex Radio. This static IP was put on the Flex at my home and it worked perfectly. Everything in his home works perfectly but the connection to the Flex. I even went so far as to confirm that the Spectrum modem was in bridge mode with Spectrum.

I have worked a many large complex networks for over 25 years, but this little one has me to the point that I now believe we have a software issue. Our next step will probably be a fresh reload of Windows 10 Pro.

I have not read all the above posts, however, if you connect the radio directly to the computer and the computer NIC card is set to DHCP, the computer will see the radio. As I am sure you area aware, this will give both NIC cards (radio and computer) a 169.... address with a wide subnet mask. Then, the radio and the computer should be able to communicate locally.

We do this all the time a Ham Radio shows without issue.

Then, start SmartSDR and you should see the radio in the chooser without it being a SmartLink connection.

Michael, this did not work. We loaded SmartSDR on another workstation on the same network and it works perfectly. We are going to do a fresh install to the regular Flex radio workstation. This should fix the issue. Since we are doing this Ronnie also wants to update to a SSD drive. This will make him much happier.... 73 K4CAE

Not sure if this helps but I had the exact same problem. I found mine was the firewall in my antivirus was stopping mine. Once i disabled the firewall/antivirus software for a few minutes it let me install the update.
